CHORDS AND HARMONY Music sounds are a little empty if notes are only played one at a time. It is the interaction between different notes played together that gives music its richness and color. Before describing chords let’s define a term called interval which will help us to understand how we build chords. An interval is the difference in the pitch between two notes. With some intervals, notes blend naturally together to create a pleasing or consonant sound. Other intervals create a more jarring or dissonant sound. Both consonant and dissonant intervals are used in music, ideally in a balanced way. Chords are built from the combination of intervals formed by playing three or more different notes together. The way in which we build chords and combine them is defined asharmony. Major chord A very common chord type is the major chord, which contains the root, the major third and the perfect fifth. The note which corresponds to the root gives the name to the chord. The major third interval is two tones above the root. The perfect fifth interval is three and a half tones above the root. C majorchord Minor chord Another common chord is the minor chord, which contains a root, a minor third (one and a half tones above the root) and a perfect fifth (three and a half tones above the root). C minorchord As when you compare the major scale and the minor scale, the major and minor chords create different atmospheres. The major chord can be more positive and clear and the minor chord can be more negative and dark. MUSICAL TEXTURE Musical texture refers to the number of layers that is heard when an individual listens to a musical piece and the way in which they interact in a composition. There are three main types of musical textures in music. They are monophonic texture, polyphonic texture and homophonic texture. Monophonic texture The word “mono” means one or single.Therefore we hear monophonic texture when a person sings alone without accompaniment or background music. So we can say that monophonic texture is heard when a single melodic line is performed without accompaniment. That single melody could be played or sung by one or many instruments or voices. Polyphonic texture The word “poly” means many. So polyphonic texture describes a musical texture in which two or more melodic lines of relatively equal importance are performed simultaneously. The melodic voices are independent from each other or in imitation with one another. Homorhythmic texture If all the parts have mostlythe same rhythm, the texture is described as homorhythmic. Melody and accompaniment The most common texture in Western music ismelody and accompaniment: multiple voices of which one, the melody, stands out prominently and the others form a background of harmonic accompaniment.
